To explore the genetic bias in a Chinese family suspected of having congenital nephrotic syndrome of the Finnish type (CNF).
We developed a prenatal genetic diagnosis in a Chinese family with CNF. A single heterozygous mutation (c.3213delG) was found in the foetus IId and we presumed that it was an asymptomatic carrier of the normal phenotype. Additionally, two compound heterozygous variants (c.3213delG and c.3478C&gt;T) were discovered in the foetus IIe, which were inherited from the mother and father, respectively. We performed further pathological examinations after medical abortion. Kidney histopathology and immunofluorescence results were similar to those reported in previous studies.
Prenatal genetic diagnosis of CNF still requires further research to explore the pathogenicity of suspected mutations.

However, little is known about the efficacy and feasibility of UAL during single-port access (SPA) myomectomy. The present study was performed to investigate the clinical benefits of UAL in SPA myomectomy and to provide details of the surgical techniques.
A retrospective and comparative review on the surgical outcomes of the patients who underwent SPA myomectomy with UAL and those who underwent SPA myomectomy without UAL was conducted. UAL was performed at its origin from the internal iliac artery via a retroperitoneal approach.
A total of 56 women who received SPA myomectomy were reviewed (24 patients received SPA myomectomy with UAL while 32 patients received SPA myomectomy only). The median weight of total resected leiomyomas was heavier for the patients who received UAL than those who did not receive UAL [210.0g (range 171.5-335.0g) vs. 119.0g (62.5-265.0g), p=0.023]. However, no differences in total operative time, estimated blood loss, perioperative hemoglobin changes, use of postoperative analgesics and postoperative complications between the two groups were seen.
Obtaining similar surgical outcomes between the patients who received UAL with larger leiomyomas and those who did not receive UAL with smaller leiomyomas suggests that UAL is a feasible surgical approach to reduce blood loss during SPA myomectomy. Detailed descriptions of the surgical techniques are provided in the present report.

Traditional screening tests were performed using a combination of biochemical markers and ultrasound measurements in the first and second trimesters to assess the risk of trisomies 21 (T21), 18 (T18) and 13 (T13). Cell-free DNA (cf-DNA) testing was offered (Harmony test) to pregnant women at high risk (&gt;1/280 for T21 and&gt;1/150 for T13 and T18) and a normal early morphology scan. In positive cases, prenatal sampling was strongly recommended to confirm the results by gold standard methods (QF-PCR and karyotyping). Newborns' phenotypes were corroborated after birth in all cases.
In this prospective study, 8153 pregnant women were enrolled, resulting in 390at high risk according to traditional screening tests. cfDNA testing was offered to 383 women. Traditional screening tests showed a false negative rate of 9.68% for T21. Traditional test sensitivity for T21 was 90.3%, for a false positive rate of 4.17% and a positive predictive value of 7.6%. The positive and negative predictive value for cfDNA testing was 100%. The approach used avoided invasive procedures in 91.3% of women at high risk. The prevalence of chromosomal abnormalities in the population analyzed was 1 in 164, and 1 in 210 for T21.
Our results show that offering cf-DNA testing to women at high risk in traditional tests (including those with risks &gt;1 in 50) significantly reduces false positives and, therefore, the number of invasive tests. Extending the use of cf-DNA testing to intermediate risk categories may be cost effective.

This retrospective, single-center cohort study was conducted from January 2013 to December 2018. Of 277 GnRH antagonist IVF/ICSI cycles in women with anti-Mullerian hormone (AMH) ?5μg/L, 170 cycles receiving the combination of r-FSH and HMG (77 with HMG added at the beginning of the GnRH antagonist cycle and 93 with HMG added after GnRH antagonist administration) and 107 cycles receiving r-FSH alone were analyzed. The dynamic hormone profiles and embryonic and clinical outcomes of the patients were evaluated.
We observed significantly lower serum LH levels in the r-FSH+HMG groups during ovarian stimulation. The serum estradiol and progesterone levels were lower in the r-FSH+HMG groups on the trigger day. Nevertheless, there were no significant differences with respect to the number of oocytes retrieved, maturation, fertilization, blastocyst formation rate or ovarian hyperstimulation syndrome (OHSS). The implantation and live birth rates were increased in the r-FSH+HMG groups compared with the r-FSH alone group, with no statistical significance.
HMG for LH supplementation in the GnRH antagonist protocol for patients with high AMH is not significantly superior to r-FSH alone in terms of ovarian response and pregnancy outcome. Nevertheless, HMG supplementation might be appropriate for women with an initially inadequate response to r-FSH or intracycle LH deficiency.
